ELECTRIC CLEANING DEVICE.

Application tiled August 11, 1921.

To all whom it may concern.'

Be it known that I, CHARLES C. OATEY, a citizen of the United States,residing at Dubuque, in the county of Dubuque, State of Iowa, haveinvented certain new and useful Improvements in Electric CleaningDevices; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin theart to whichit appertains to make and use the same.

This invention relates to new and useful improvements in cleaningmachines and particularly to machines for-cleaning meat chopping-blocks,floors, or for sand-papering or dusting other surfaces.

One object of the invention is to provide a device of this character`which has an electrically driven cleaning element, the device beingarranged to be pushed over the floor, chopping-block, or other surfacesto be treated.

Another object is to provide a device of this character which includes adusting element arranged to be connected with the drive shaft and thebrush of the dusting element moved over the surface to be cleaned.

Another object is to provide a device of this character which includesmeans for feeding a liquid to the surface to be cleaned, aud to thecleaning brush, so that the surface can be more eliciently cleaned, thematerial removed from the surface being thrown into a receptacle whichis readily removable for emptying or destruction and replacement by anew one.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawing.

In the drawing: Figure 1 is a side elevation of a cleaning machine madein accordance with the invention.

Figure 2 is a bottom plan View of the same.

Figure 3 is a vertical longitudinal central sectional view on the line3-3 of Figure 2.

Figure 4 is ahorizontal longitudinal Hsectional view taken on the line 44 of Figure 3 3, above th'e motor and brush, and through the liquidreceptacle.

Figure 5 is a vertical longitudinal sectional view on the line 5-5 ofFigure 4, outwardly of the worm shaft.

Serial No. 491,540.

.Figure 6 is an enlarged central sectional View showing the brush andthe shaft mounting.

Figure 7 is an elevation of the duster attachment partly in section.

Referring particularly to the accompanying drawing, 10 represents ahousing of suitable size and shape, and which is provided wlth a bottomwall 10 having an opening 11 formed therein. In the rear portion of thehousing 10, and supported by suitable brackets 11, is an electric motor12, having its shaft 13 extending transversely of the housing andprovided with a bevel gear 14 on the outer end. In the forward portionof the housing, and at opposite sides thereof, are the socket bearings15 and 16, which support the internally threaded members 17 and 18,respectively. Removably screwed into the members 17 and 18 are theexternally threaded ends of the brush shaft 19. The member 174has a wormgear 2O which meshes with a. worm shaft 21, extending longitudinally inthe housing 10, and supported in the brackets 22. One end of the wormshaft 21 has a bevel gear 23 which meshes with the bevel gear 14 of themotor shaft. The outer end of the member 18 is disposed through anopening in the side of the housing and is externally threaded for apurpose which will presently appear. On the side of the housing,surrounding the said opening, is a threaded flange 24 onto which isscrewed a cap 25 for protecting the end of the member 18, when the sameis not being used twith the duster which will be later referred Carriedby the housing and extending longitudinally underneath the bottomthereof, are the runners 26, which serve to supportA the device in itsmovement over the article being cleaned. These runners are detachablysecured at their lforward ends to the housing by means of the set screws30, while they are connected at their rear ends by means of the bolts 47which pass loosel through openings in the lugs 28 and whio are threadedwithin openings formed in the runners, as shown at 48. Disposed betweenthe lugs 28 and the runners and encircling the bolts 47 are the springs49, which noi'- mally ur e the housing and the runners apart. T esupporting runners are slightly longer than the housing and the forwardends thereof overla the lower portion of the housing. The orwardportions of the runners 26 are cut away to form an opening 26 whichopening registers with the opening 11 formed in the bottom of thehousing and through which the bristles of the brush 19 project foraction u on the surface to be treated. Hinged 'at t e rear end of thehousing is a door 31 which -is arranged to close an opening 32 in theside wall of the housing, suitable fastening means 33 being provided onthe door and housing for holding the door in closed position. Within thehousing, directly inwardly of the opening 32, is a metal receptacle 34having its forward end open and having disposed therewithin a removableaper or fiber container 35, the o en end of which is disposed in theopen en of the receptacle. Carried by the lower side of the open end ofthe receptacle is a downwardly and forwardly extending scoop blade 36,the same being in position to irect the material from the brush into thecontainer. Secured to the lower face of the forward end of the bottomwall 26 are the surface engaging rollers or casters 37.

Mounted in the housing, above the brush 19, is a liquid container 38,the lower end of which is formed with a dischar e spout 39 fordelivering liquid to the brus Detachably connected to the sides of thehousing 10 are the upwardly and rearwardly extending bars 40, the upperends of which are connected by the handle bar 41, which is grasped bythe operator to push the machine over the surface to be cleaned.

Adapted to be screwed onto the outer end of the member 18, when the cap25 is removed, is the threaded socket 42 of one end of a flexible shaft43. The other end of the shaft is arranged to be detachably secured inthe socket 44 of the dusting brush 45, as clearly seen in Figure 7 ofthe drawings.

Carried by the upper side of the housing are the handles 46 which areadapted to be grasped by the operator when moving the device over thesurface of a meat choppingblock.

What is claimed is:

1. A cleaning device including a housing, detachable supporting runnerscarried by the housing and formed to rovide an opening, a brush mountedwit in the housing and operating through the opening, and means fornormally urging the runners and housing apart.

2. A cleaning device including a housing, one end of the bottom of whichis located above the plane of the other end, the said housing belngprovided with an opening in the lower end ofthe bottom, detachablesupporting runners carried by the housing and formed to provide anopening registering with the opening in the housing, and a brush mountedwithin the housing and operating through the openings.

3. A cleaning device including a housing, having one end portion thereoflocated above the plane of the other end, the lower end of the housinghaving an opening therein, and a slanting portion extending between thehigher end and the lower end, detachable supporting runners carried bythe housing and formed to provide an opening registering with the firstopening, and a brush mounted within the housing and operating throughthe openings.
